China's ice and snow industry is transitioning from its early development stage to a new phase of high-quality development. This study retrieved articles from core journals in the China National Knowledge Infrastructure (CNKI) database published between 2015 and 2025, using "ice and snow sports" and "industry" as keywords. After screening, 169 articles were included and systematically reviewed using thematic analysis. The results show that China's ice and snow industry faces management challenges including a "top-heavy" industrial chain (weak downstream links), unbalanced regional development, a shortage of interdisciplinary talent, insufficient core technologies, superficial industrial integration, and high pressure for green development. The study proposes solutions such as improving the industrial chain integration mechanism, optimizing spatial layout, building a multi-level talent cultivation system, strengthening technological innovation, deepening "ice-snow+" integration, and improving the standardization system, thereby providing a theoretical reference for the high-quality development of the ice and snow industry.

Rapid urbanization and the continuous improvement of the land expropriation policy system have led to a continuous expansion of the landless farmer population, making their social security a crucial and unavoidable issue in the process of achieving common prosperity. This paper takes the currently effective social security policy texts for landless farmers in China as the object of study, employs grounded theory for three-level coding analysis, and constructs a theoretical model of the policy design logic. Based on this, the study found that the design of social security policies for landless farmers encompasses a complete logical loop, from target identification to implementation and operation, and then to external support. These three aspects are progressive and internally coupled: the policy design takes a "system for strictly and precisely defining beneficiaries " as its logical starting point, ensuring targeted allocation of resources through standardized and comprehensive target identification principles, multi-layered and dynamic identification and implementation processes, and differentiated and precise assistance strategies; it uses a "layered and diversified implementation system" as its operational hub, embedding flexible, diversified, and differentiated institutional arrangements in the payment, fundraising, operation, and disbursement stages to form an incentive-compatible operating mechanism; and it uses a "comprehensive and multi‑tiered support system" as its external support.

This study selects sample data of China's A-share listed companies from 2011 to 2023 to analyze the relationship and mechanism between supply chain stability and the development level of new quality productivity. The results show that supply chain stability is positively correlated with new quality productivity, that is, a stable supply chain contributes to the cultivation of new quality productivity. Heterogeneity analysis indicates that this positive impact is more significant in enterprises with high supply chain concentration and high financing constraints. This study enriches the research on the influencing factors of new quality productivity and the economic consequences of supply chain stability, and has certain practical reference significance.

The digital China initiative, leading sports nation initiative and healthy China initiative together with the cultural and tourism integration has set up a basis for the development of outdoor sports and tourism in terms of policies. With the digital economy driving more change, people's need for outdoor entertainment is not just about seeing things around them; it is becoming more individualized, immersive, secure and interactive. But there also are short-comings: Information is not symmetrical, supervision of safety is insufficient, products all look the same, and it's hard to match supply and demand. And it is also important tool which could deal with the supply problem. Research about existing digital sports, smart tourism, and outdoor sports industry is still very scattered and no one has carried out in-depth study of the connections between digital empowerment, resource development, sports tourism integration. The paper carries out an organized literature review to gather releas: In this paper we try to create a theoretical frame covering the areas of technologic supply, resources' attribute and integrative ways in industries. Theoritically can help us understand how value is created for sport tourism destination in the digital economy. Practically, it is beneficial to help local governments, scenic areas, outdoor sports enterprises and other units in carrying out resource allocation, product creation, smart management etc., so as to build an efficient high-quality outdoor sports industry system.
